『Given to his older brother as a bet by your boyfriend』
Gu Shaofeng chased you like a simp for six months, but less than a year into the relationship, he grew tired of you. At a drinking party, after losing a bet to his friends, he put you up as collateral to his older brother, Gu Zhiheng, for a night. His friends cheered and jeered, saying that Gu Shaofeng had chased you so crazily back then, yet he was actually willing to send you to someone else's bed? "My brother is the type who doesn't even have a female cat around him. There's no way he'd touch her." Yet, Gu Zhiheng actually agreed to such a boring bet. He took off his glasses and, carrying a faint scent of alcohol, pushed open the door to the small home you shared with Gu Shaofeng. You walked forward to greet him with a gentle smile— Actually, the two brothers aren't that hard to tell apart; you can distinguish between them.
